In the figure shown below, a light ray enters the air-plastic interface at the angle of incidence 0, = 35.00. Then it refracts in the plastic material at 02 = 18.0, The index of refraction of water (nwater) is 1.33. Answer the following problems based on this information. A. The index of refraction for air (nair) is [ Select ] and the index of refraction of the plastic material (nplastic) is [ Select ] B. Now the light ray falls on the plastic-water interface, the angle of incidence at this interface is [ Select ] degrees. When the light ray refracts from the plastic-water interface, the angle of refraction in water, 03 is [ Select ] degrees. C. The speed of light in plastic is [ Select ] m/s, and the speed of light in water is [ Select ] m/s D. As the light passes through the plastic-water interface, the angle at which the light ray travels parallel to the interface is called [ Select ] , and the value of this angle is [ Select ] for the plastic-water interface. E. Some part of the light (EM wave) will get reflected from each boundary/interface. When the light is reflected from the air-plastic interface, the phase of the reflected light wave will be [ Select ]
